@Gary Watson I was thinking of trying this exact same thing. Did it work? I've done this at e.g. hotels for connecting an old Roku to the wifi and had success.
My other main questions would be 1) how often does captive make you re-login, 2) does the watch reliably stay connected to the wifi when it's not connected to the phone, 3) how quickly does the watch battery drain in this case?
Also, my understanding is that you can pretty seamlessly switch between devices on the wifi, it just kicks the previous device off. So I imagine you can pretty easily switch between phone and watch in that way, right? Maybe you have to re-login via laptop to switch from phone -> watch though?
